2In O, ethane, the propane one or more, preferred supercritical CO
2As working gas.
Below to adopt supercritical carbon dioxide, the production system with two groups of dye cycle devices is that example is introduced dyeing production technology of the present utility model:
With reference to illustrated in figures 1 and 2, the carbon dioxide that comes out from fluid liquid storage tank 11 cools off laggard high-pressure pump 13 pressurizations (pressure is 10-45MPa) of becoming owner of through subcooler 12, enter preheater 14 heating (temperature is 50-230 ℃) then, supercritical carbon dioxide after the preheating enters from the supercritical fluid import/export above or below one of them dyestuff still 21, contact with dyestuff, the carbon dioxide that has dissolved dyestuff enters in the dyeing caldron 22 via the supercritical fluid import/export by the dye distribution device, contact with fabric from inside to outside or from outside to inside by distributor, dyestuff is adsorbed onto on the fabric, carbon dioxide is then discharged from the below or the top of dyeing caldron, enter dyestuff still and dyeing caldron after boosting by high-pressure circulation pump more again and carry out the dyestuff dissolving, the circulation of fabric absorption is finished until dyeing.After dyeing finishes, by valve supercritical carbon dioxide is switched in another dyestuff still and (to install fabric in advance), repeat above-mentioned steps and carry out second batch dyeing, thereby realize continuous dyeing incessantly.When end is produced in whole dyeing, system switches to great circulation system with carbon dioxide by the valve closing dye cycle, the carbon dioxide that is dissolved with dyestuff makes the solubility of dyestuff in carbon dioxide approach zero through decompression, intensification, enter the dye separation still then and carry out dyestuff and reclaim, it is that liquid is got back to the fluid liquid storage tank and recycled that carbon dioxide then enters condenser condenses.
Next specifically describe the course of work of each device:
Start is prepared: start cold machine circulation, start cold machine, chilled water temperature is controlled to be 3-8 ℃, opens heating furnace or the steam boiler and the circulatory system, and control heat medium temperature is 60-180 ℃.About 30 minutes of time.
The intensification of boosting: low rate start master high-pressure pump 13, treat to be modulated to after working properly the frequency of setting, with the carbon dioxide intensification of boosting, Pressure control realizes that by automatic pressure control valve PV1 pressure is (10-45MPa); By preheater 14 carbon dioxide is warming up to 60-180 ℃, makes carbon dioxide become supercriticality, enter dyestuff still Da/Db, dyeing caldron DA/DB.After reaching predefined dyeing condition, stop main high-pressure pump, refrigerator and heating furnace; Close AJ2, AJ15, start high-pressure circulation pump, carry out dye cycle.
Dye cycle:
With the work of DA dyeing caldron is the example explanation:
Circulation 1: supercritical carbon dioxide enters from the supercritical fluid import/export below one of them dyestuff still by valve AJ3 or AJ4, contact with dyestuff, the carbon dioxide that has dissolved dyestuff enters in the dyeing caldron via the supercritical fluid import/export by the dye distribution device, make dyestuff be adsorbed onto on the fabric equably by distributor, carbon dioxide is then discharged from the kettle top by valve AJ14, enter and enter the cyclic process that dyestuff still and dyeing caldron carry out dyestuff dissolving, fabric absorption after high-pressure circulation pump 24 boosts again, finish until dyeing.
Circulation 2: supercritical carbon dioxide enters from the supercritical fluid import/export of dyeing caldron top by valve AJ12, contact with dyestuff, the carbon dioxide that has dissolved dyestuff enters in the dyeing caldron via the supercritical fluid import/export by the dye distribution device, make dyestuff be adsorbed onto on the fabric equably by distributor, carbon dioxide is then discharged from the kettle below by valve AJ10, enter and enter the cyclic process that dyeing caldron 21 carries out dyestuff dissolving, fabric absorption after high-pressure circulation pump 24 boosts again, finish until dyeing.
The switching of dyeing caldron: after one of them dyeing caldron dyeing finishes,, promptly finish the switching of dyeing caldron by closing and Open valve AJ7, AJ8, AJ11, AJ12.
The separation of dyestuff is reclaimed: when end is produced in package unit dyeing, stop high-pressure circulation pump 24, start main high-pressure pump 13, open valve AJ15, at this moment supercritical carbon dioxide is by automatic regulating valve PV1 decompression and heater 31 heating, become gaseous state, wherein Rong Xie dyestuff is desorbed, and enters dye separation still 32 and reclaims with the carbon dioxide dye separation.
The recovery of carbon dioxide: the gaseous carbon dioxide in separating still behind the separation dyestuff enters condenser 33 and is condensed into liquid, enters the fluid liquid storage tank then and reclaims, in order to recycling.
The release of dyeing caldron: after dyeing caldron dyeing is finished, carry out pressure balance between two stills earlier by valve AJ13, AJ14, to reduce the consumption of carbon dioxide, valve-off AJ8, AJ10, AJ12, AJ14 then, open CJ1 and carry out the emptying exhaust, the pressure in dyeing caldron is zero.
The taking-up of fabric is packed into: after the still internal pressure is zero, with clip pneumatic or manual unlocking dyeing kettle, mention kettle cover with cylinder, access the internals of having twined fabric with overhead traveling crane then, good fabric is dyed in taking-up, changes the fabric that does not dye, and covers kettle cover in the still of packing into, the clip that closes is waited for dyeing course next time.
Packing into of dyestuff: the dyeing caldron of this device utility model, its indoor design have two dyestuff accommodation apparatus up and down, make the carbon dioxide that enters at first pass through the dyestuff accommodation apparatus with dissolving dye.The loam cake of dyestuff accommodation apparatus is detachable, is used to the dyestuff of packing into.
Above disclosedly only, the utility model carries out the preferred embodiment of the production system of continuous dyeing for adopting supercritical fluid, certainly can not limit the interest field of the utility model with this, therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
